Essentials
This level consists of a series of skull switches that must be pressed to reveal more of the map.

Quickly kill the zombies and imps in front of you, then press the first switch to your right to raise some steps up to the platform with the super shotgun. Climb up another step to get a megaarmor and press the second switch next to it to lower the east wall and reveal Hell knights, then walk south up some pentagram steps to confront one or two chaingunners and an arch-vile who are protecting the third switch. Press this switch then go back to the starting area, kill any revenants that have been revealed then climb some more pentagram steps and turn left to see another arch-vile protecting the fourth switch; after pressing it, go back down to the third switch to see that the wall behind it has lowered, revealing another arch-vile guarding a rocket launcher and the fifth switch.

Press the fifth switch, then go back to where you found the fourth switch to see that a wall has lowered revealing a pack of imps and one or more revenants. Climb up the steps on the west side of the room to get to the revenants' ledge and follow it round to the sixth switch, which will lower the wall that the fifth switch was sitting on to reveal a chamber with a baron of Hell, one or more knights and an arch-vile standing on a ledge. Press the seventh switch on the east fence to lower the wall next to the arch-vile's platform, then climb up there to find the eighth switch that will open the area in the south-west corner of the map. Go there and kill the knights that have been revealed, then step round the marble block to find the ninth switch on the south fence; step out quickly after pressing it as the block will lower and release revenants.

Go back to the north-east area, where the wall has lowered to reveal a staircase with another arch-vile, then go up the steps to a room with imps and one or two pain elementals who are guarding a cache of ammo and a megasphere. Kill the knight and baron blocking the steps then climb up to a plasma gun and the tenth switch, which will lower the wall at the south end of the map and release a pack of revenants and barons. Push through these monsters to the eleventh switch and press it to open another chamber to the north-east containing more barons, grab the megasphere in this chamber then press the twelfth switch behind it to open the exit room to the south. A cyberdemon blocks your way to the exit switch, which will often after several seconds, but you should leave it alone as a large number of knights will teleport in and kill it through infighting.

Secrets

 * 1) After pressing the third switch and lowering the wall south of the starting point, look towards the column with the lion heads on it and press on the wall below it to find a teleporter. This takes you inside of the column where you will get a supercharge. (sector 111)
 * 2) After pressing the ninth switch and lowering the wall behind you, press on the south side of the column with the satyr faces on it to lower another supercharge. (sector 153)
 * 3) In the room with the tenth switch, lower the satyr block to find a BFG9000. (sector 170)
